Understanding Spam Rentals & Fraudulent Charges

When it becomes easier for good customers to rent online, it also becomes easier for bad actors to try. Older self-storage rental systems usually had 3 to 6 pages creating more friction. That extra friction slowed down both real renters and fraud attempts. 

Our newer one-page checkout makes renting faster and easier, similar to modern eCommerce like Shopify. This improves conversion rates and helps more real customers complete rentals. 

This is normal across eCommerce. Most industries deal with this every day. 

The difference is that self-storage has traditionally relied on slow, multi-step rentals, so many operators are seeing this challenge for the first time. 

There are three separate vendors involved in every online rental: 

The payment processor and the renter’s bank make that decision, not Storagely.

They decide if a card is:

Example: “Do Not Honor” 

If you see a decline message like: Do Not Honor 

This message is coming from the payment processor or the customer’s bank. It does not come from Storagely. It usually means the bank declined the charge but did not give a specific reason. 

Important to know 

The system must try the payment first before a decline code like this can be returned. That means the card was submitted for authorization, and the processor or bank made the final decision.

There are important limits to fraud prevention: 

(With Conversion Trade-Offs) 

While there are more aggressive fraud prevention measures we could implement, each additional layer of security creates a direct tradeoff with conversion rates. Stronger restrictions often introduce more friction for legitimate customers creating longer checkout times, more verification steps, failed validations, blocked transactions, and increased abandonment during the rental process. 

In self-storage, where speed and convenience are major drivers of online rentals, too much friction can significantly reduce completed move-ins from real customers. The goal is not simply to block every possible fraudulent attempt, but to create the right balance between protection and conversion, stopping bad actors without making it harder for legitimate renters to do business with you. 

Fraud prevention is not only a website issue. Your FMS settings and payment processor settings are equally important. We strongly recommend reviewing: 

Examples: 

Many processors allow stricter fraud screening that may not be enabled by default. 

If a fraudulent rental gets through: 

Faster checkout improves rentals. But faster checkout also requires stronger fraud management. 

This is not a failure of the website, it is a shared responsibility across: 

The goal is not to eliminate all fraud (which is impossible). The goal is to reduce fraud while still allowing real customers to rent easily.

That balance is where strong operators win.
